What does this pattern mean?

Can I ask you what does this pattern mean?
A friend of mine told me:
''I am a stocks trader, not a bitcoin trader but I have seen this pattern a lot of times in years of stocks trading, and this means up pump''

Was he trolling me? I am a newby, by looking at the chart I can' t see any indicator, he doesn't even utilize a candlestick graphic.

You are more experienced than me, maybe. Looking at this graph what could you assume?
Which kind of indicators are utilized here?

This chart vaguely resembles a descending triangle pattern - a downtrend combined with a horizontal support. It does not use any indicators - it just a close line chart with volumes. I'd say that we could assume by looking at this chart that there is a strong support area near $3,800.

As you can see, at the end of the graph the volume starts to pump, but it's ''red volume'' what that that mean?

The "red volume" is just a normal volume histogram bar, which appears during a bearish candle. If the price rose for a period, the volume bar is drawn green, if the price falls, the volume is drawn red.
